The present work investigates the potential use of luminescent materials in tandem systems for diagnostic radiology. MgB₄O₇:Ce,Li (MBO) (Z_eff = 8.1), borate glass (80–20MBO) (Z_eff = 8.3) and Al₂O₃:C (Z_eff = 10.9) are tested as optically stimulated luminescence (OSL) detectors. The first part of this work evaluates the energy response of the detectors exposed to standard radiation qualities, followed by the calculation of the tandem curve based on the ratio of the energy responses of the 80–20MBO/Al₂O₃:C and MBO/Al₂O₃:C detector pairs. The results indicate that the energy response of the OSL materials overresponds, for a low energy photon beam, by an order of 6 for Al₂O₃:C, 3.5 times for 80–20MBO and 1.7 times for MBO. The highest uncertainty in this measurement is found for Al₂O₃:C (16.6%). The results of the tandem analyses indicate that both pairs of detectors can be used for this application, although MBO/Al₂O₃:C had higher efficacy, compared to 80–20MBO/Al₂O₃:C. In both cases, the tandem curves are effective for energies below 50 keV, where steep energy behavior is observed and the highest uncertainty is observed for MBO/Al₂O₃:C (~18%).

本工作调查了发光系统在放射诊断串联系统中的潜在用途。测试了MgB ₄ O ₇：Ce，Li（MBO）（Z _eff  = 8.1），硼酸盐玻璃（80–20MBO）（Z _eff  = 8.3）和Al ₂ O ₃：C（Z _eff  = 10.9）作为光激发发光（OSL）检测器。这项工作的第一部分评估了暴露在标准辐射质量下的探测器的能量响应，然后根据80–20MBO / Al ₂ O ₃：C和MBO /的能量响应之比计算串联曲线。铝₂ O ₃：C检测器对。结果表明，对于低能量光子束，OSL材料的能量响应对Al ₂ O ₃：C的响应约为6倍，对于80-20MBO为3.5倍，对于MBO为1.7倍。对于Al ₂ O ₃：C（16.6％），发现该测量的最高不确定性。串联分析的结果表明，尽管与80–20MBO / Al ₂ O ₃：C相比，MBO / Al ₂ O ₃：C的功效更高，但两对检测器均可用于该应用。在这两种情况下，串联曲线对于低于50 keV的能量均有效，其中观察到陡峭的能量行为，并且对于MBO / Al ₂观察到最高的不确定性O ₃：C（〜18％）。
